Is it worth it to save some seeds for the following season in your personal experience?

I have a big shipment of amazing hot pepper seeds coming for the 2023 season. They should arrive on Friday.

The listing said about 10 seeds per packet but from the photos some have more. If I plant 10 of each variety and save the extra for 2024, will they likely germinate? Or should I just use them all this year?

I don’t have a ton of space but don’t want to lose seeds in storage. Have any of you saved seeds over a year and had success? Any tips? Thanks!
